Defined in header <cmath>
float       asin( float arg );
double      asin( double arg );
long double asin( long double arg );
double      asin( Integral arg );		(since C++11)

Computes arc sine of arg.

Parameters

arg

-

value of a floating-point or Integral type

Return value

Arc sine of arg in radians in the range of [-π/2; π/2] radians.

Domain error occurs if arg is outside the range [-1.0; 1.0]. NaN is returned in that case and FE_INVALID is raised.

std::asin(+0) returns +0. std::asin(-0) returns -0.
